Moreover, myeloid cells also expressed high levels of arginine (ARG) that binds to intercellular adhesion molecule 1 (ICAM1) in follicular cells, whose expression levels have been shown to be increased in PTC, poorly differentiated thyroid cancer (PDTC), and anaplastic thyroid cancer (ATC) and which has been proven to be an effective therapeutic target in advanced thyroid cancer (55, 56). The gene discussed is ICAM1; the disease is thyroid gland carcinoma.
